For cylindrical black strings, NED Lagrangians with a Maxwell weak-field limit cannot produce regular purely electric or dyonic cores; regular magnetic Bardeen/Hayward analogues exist but violate causality near the axis.

Unimodular gravity with Maxwell sources yields regular black strings and BTZ black holes supported by a radially varying vacuum energy Λ(r) obtained as an integration constant.
Exact cylindrically symmetric black-hole and black-string solutions sourced by the Dekel-Zhao DM profile exhibit horizon disappearance above a critical inner slope and curvature singularities absent in the vacuum case.
Black bounce geometries exist in 2+1D f(R) gravity with scalar-nonlinear electrodynamics matter, including vanishing scalar curvature solutions whose viability is checked via scalaron mass and energy conditions.
